The second user, also known as the guest account user, is a temporary user who cannot access your primary profile. They cannot use your phone to make calls, send SMS messages, or access any of the data or apps. They are limited to using their phones to install apps and save data. A button above the quick settings on the top will allow you to create it. You can even lend the phone to someone else to store their info if you set it up as a user and not a guest account.

In addition to its security features, WhatsApp hides your messages from prying eyes. You need to click on the Settings app on the home screen to do this. After that, turn on Touch ID or Face ID under Accounts > Privacy & Screen Lock to prevent unauthorized access to your chats.
